F11 Alloy Steel Round Bars

F11 alloy steel round bars are commonly used in high-temperature and pressure applications, such as in the petrochemical, power generation, and aerospace industries.

F11 alloy steel round bars offer high-strength for demanding applications, meeting ASTM standards. Known for its composition, properties, and reliability:

Chemical Composition:

Mechanical Properties:

• Tensile Strength: 415-585 MPa
• Yield Strength: 205-415 MPa
• Elongation: 20-30%
• Hardness: Typically in the range of 187-229 HB (Brinell hardness)

Physical Properties:

1. Density: The density of F11 alloy steel is approximately 7.85 g/cm³, similar to most carbon steels.
2. Melting Point: The melting point of F11 alloy steel is typically around 1420-1470°C (2588-2678°F), depending on the specific composition.
3. Thermal Conductivity: The thermal conductivity of F11 alloy steel is approximately 42-49 W/(m·K). This property indicates its ability to conduct heat.
4. Specific Heat Capacity: The specific heat capacity of F11 alloy steel is typically around 460-480 J/(kg·K). This property denotes the amount of heat required to raise the temperature of a unit mass of the material by one degree Celsius.
5. Electrical Conductivity: Alloy steels like F11 typically have relatively low electrical conductivity compared to other materials.
6. Magnetic Properties: F11 alloy steel is generally ferromagnetic, meaning it exhibits magnetic properties under the influence of an external magnetic field.

Manufacturing Standards: F11 alloy steel round bars are typically manufactured to meet ASTM A182/A182M (Standard Specification for Forged or Rolled Alloy and Stainless Steel Pipe Flanges, Forged Fittings, and Valves and Parts for High-Temperature Service).

Heat Treatment: F11 alloy steel is commonly heat-treated by quenching and tempering to achieve the desired combination of hardness, strength, and toughness.

Applications: F11 alloy steel round bars are used in applications such as valves, flanges, fittings, and other components in high-temperature and pressure environments, particularly in oil refineries, chemical plants, and power generation facilities.
